HTTP_PROXY is set for Slack plugin to connect to Slack servers.
However Oauth plugin should not use the proxy for its outbound connection thus failing to connect to the OIDC server.
This is due to the lack of setting allowing to exclude domains for proxy connections
Adding a setting like HTTP_PROXY_EXCEPTION accepting values like “internal.org” which should exclude proxy settings for all connections to *.internal.org.
